Problems solved by technology

[0002] The traditional soil nailing wall slope protection construction drilling equipment uses a crawler-type screw bolt drill. During the drilling process in soft soil layers, the construction speed is slow, the dust is large and the construction cost is high. Often, the foundation pit cannot be closed in time after excavation. The soil around the foundation pit is prone to cracking or even slipping after rain
Therefore, in the construction process of soil nailing wall protection for slopes in soft soil layers, the traditional screw bolt drilling rig has certain limitations in terms of construction speed, environmental protection and cost.

Abstract

The invention relates to a soft soil layer foundation pit side slope anchor rod drilling device. The soft soil layer foundation pit side slope anchor rod drilling device comprises a mounting bracket arranged on a breaking hammer head of a hydraulic breaking hammer, a first mounting plate arranged at the bottom of the mounting bracket and a steel pipe arranged on the first mounting plate and used for drilling. The steel pipe is arranged on the breaking hammer head of the hydraulic breaking hammer to form a drill rod, and the hydraulic function of the breaking hammer head is used for ejecting the steel pipe into a soil layer, and a hole is formed after the steel pipe reaches the design depth. The soft soil layer foundation pit side slope anchor rod drilling device is suitable for soft soil layer side slopes.

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to a soft soil foundation pit side slope bolt drilling device. Background technique [0002] The traditional soil nailing wall slope protection construction drilling equipment uses a crawler-type screw bolt drill. During the drilling process in soft soil layers, the construction speed is slow, the dust is large and the construction cost is high. Often, the foundation pit cannot be closed in time after excavation. Cracking or even slipping of the soil around the foundation pit is prone to occur after rain. Therefore, in the construction process of soil nailing wall protection for slopes in soft soil layers, the traditional screw bolt drilling rig has certain limitations in terms of construction speed, environmental protection and cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a soft soil layer founda...
